Chapter 6 Maintaining the Router

Removing and Replacing the Blower Module

Step 2 Visually check the condition of the air filters to determine whether to clean them or install new replacements.

•Dirty—You can vacuum or replace the filters.

Caution Do not try to vacuum the air filter while it is installed in the chassis. You must remove the air filter completely before you clean it to prevent contaminants from being drawn into the router.

•Worn or torn—If the filters appear worn or torn, dispose of them in a responsible manner and install replacement air filters (ACS-GSR6-FLTR=).

Step 3 Open the air filter door and install the new or cleaned air filters.

Note An arrow located on the edge of each air filter frame that indicates the direction of air flow. Always install the air filter with the arrow pointing in toward the RP and line card cage.

Removing and Replacing the Blower Module

The illustrations in this procedure represent both the original and newer enhanced capacity blower modules for the Cisco 12006 and Cisco 12406 series routers; blowers that shipped with original systems, and enhanced capacity blowers that ship with current systems. If you are replacing an:

•Original blower module (GSR6-BLOWER=)—Use an original blower module or an enhanced capacity blower module as a replacement.

•Enhanced capacity blower module (12000/6-BLOWER=)—Use an enhanced capacity blower module as a replacement.

Note Compared to the original blower modules that shipped with Cisco 12006 and Cisco 12406 series routers, airflow capacity for new enhanced blower modules is increased by nearly 40 percent to provide additional cooling to the chassis. The new fans operate at a higher speed to provide improved airflow, so you may notice increased sound generated from the new blower module.
